More- over, the bract above the neuropodium is more flattened and tongue-shaped than in the stem-form and lacks the terminal stylode. Otherwise, in the shape of the head, in the form of the minute elytral vesicles and in the structure of the feet and bristles these specimens are indistinguish- able from the European form. I have not been able to compare the scales from the anterior region of the body, for these are all lost from the present specimens, which are in rather poor condition. They are all incomplete and the largest measures 20 mm. by i mm. without the feet for about 80 â IMM I Fig. 15. Sthenelais limicola, var. novae-zealandiae.
